Hi Erm, I'm sorry, i put the wrong dump program ! It dumped the $2000 to $3000 memory segment… The right program will (REALLY) scan the 0-2000 memory offset. P & Wav: BiosDump.zip LOAD it, and wait the "9/4" (STOP AT LINE 4) And Save it (SAVE"DUMP") Your previous wav was clean and working. I'm sorry...

Thanks Erm, The RomCheck tool is an ASM program how read the original BIOS datas from a REM and get ROM BIOS. It will give you all values/address changed by the If hardware. The Bios backup retrieve the Bios $0-$2000 and store it in a DIM value. Run the program and save it as a P file, the Bios will...

to retrieve a binary bloc to a text file... Or save this bloc in a binary file, and recall it to a rem. In cas of a screen filling at the start, you had to save the D_File screen in P,BIN ou SCR and patch the selected file in "file explorer". P_D_File.JPG The file had to be saved in 16k un deflated...

Hi, If anyone can dump the Zx81 Monitor rom with the If expansion board, i will able to rebuild the original ROM ! The existing Rom is a dump from 2800h to 2A00h, but a part of this Rom is redirected to the $0000-$2000 (?) address to intercept the LPRINT command, like the G007 HR card. I don't know ...

A 1 million dollars program.

Don't share to be wealthy.

Yes !
I had to have a look to this window…

Thanks Greg, my favorite user.

[Edit: download updated, menu moved to the main "Tools" menu, and binary D_File save added.]

Hi, The simply way to save a memory bloc like the D_File memory segment, in Vb81 XuR to TASM... 1) Draw a pretty picture with the Easy Draw or the bitmap digitalizer window. 2) Target the D_File in the binary viewer. 3) Open the disassembler windows. 4) Select the lower and the upper limits memory o...

Hi, For a Spectrum or a Zx81 ? For Windows or something else ? Zx81: Vb81 XuR > Tools > D_Files tools > digitalize a bitmap picture. http://zx81.vb81.free.fr/images/digit.gif Can export it in BAS (basic text file 24x32) or text file (TXT)… but, throw the screen directly to the Zx's D_file (save it i...

Thanks Rafael, it's a good idea.
